By means of my invention I am enabled toproduce a reel which will be'very compact and take up the least possible space. When. .i the reels are to be placed underneath the cord-shelf, the may be mounted side by side, since the reels ave but little width. Where, however, the plugs are located very close tom gether onthe key-shelf, each frame may be 4 made of a length ,sufiicient to hold two sheaves,-and thulsacconmrodate two cords, Lvhlifle reducing the number of frames by one- .2 a a I. In a switchboard-cord reel, the combination with a frame, of a sheave-ada ted to hold' the switch-dord, and" from which the cord 'may be led for'use, a drum between the frame and sheave'around which the idle portion of'the cord'i's wrapped, and mechanism' ada ted to operate said sheave to return the cor to normal position after use.

'2 In a switchboard-cord reel, the combi 2 5 nation with a frame, of a cord-sheave rotata I 'bly secured to the frame, a spring connectin said frame and sheave, the cord bein le from said sheave against the tension 0 said spring; and a drum around which the idle 3o portion of the cord'is Wrapped; 7

4. In a. switchboard-cord reel, the combination with a frame adapted to be supported adjacent the key-shelf of a switchboard, of a gg' sheave rotatably secured to said frame, and

from which the switch-cord is led to the keyshelf, the cdrd being secured near its fixed end to the sheave,a drum around which the portion of the cord between said connection eamus fixed end is wrapped, saidportion u on the Withrawal of the cord from the s eave," being unwrapped from said drum and wrapped thereon in a reverse direction,

andmechanism adapted to operate said 5 5 sheave, ,to return said'cord to its normal position after use. a

5. In as witchboard cord reel, the combinationwith a frame adapted to be supported adjacent the key-shelf of a switchboard, of a disk rotat'ably mounted upon said frame and having an annular flange secured thereto, formin with the diska sheave for the switch- -cord;'tl 1e cord being led from said sheave to v v the key shelf, and a spring carried by the 5 adapted 'to' operate the sheave; to ree nation witha-frame, of a sheave adapted to turn the switch-cord to its normal position after use. v

6. In a switchboard-cord reel, the combination with a frame-plate ada ted to be su ported adjacent the key-shell of a switchboard, of a sheave for a switch-cord, said cord passing through an opening in the side of the sheave, and being secured near its fixed end'fto the sheave, a drum secured to the frame-plate, a spindle passing through said drum serving as a bearing for said sheave, the portion of said cord between its attachment to said sheave and its fixed end being wrapped around said drum and being'unwrapped therefrom and reversel wrapped thereon u on the withdrawal 0 saidcord from the s eave foruse, lugs projecting from the rear of the drum and forming a chamber between the drum' and sheave, and a helical s rmg -within said chamber connecting said 5 rum-and sheave, said spring being adapted to operate said sheaveto return the cord to its normal position after use. 7. A switchboard-cord reel comprising a sheave for switch-cords, having a'p'eripheral groove of varying width to accommodate the varying diameter of a switch-cord. 8. A switchboard-cord reel comprising a disk provided with an annular flange forming with the disk'a s'heavel for'. the switch-cord, said flange being curved to 'form seats to acswitch-cord. v g 9.
